As it is my personal experience about shareit is that it is a free application that lets you send your content at lightning speed between devices including: photos, vedios, app, songs etc. With the help of which you can easily share files from Android to iPhone, to PC and even Mac or cell phone to cell phone, as sharing file through bluethoot takes much time and not efficient but through the shareit transfer files on the go.so friends use it once its awsome app n userfriendly also .
